Reaction Conditions

Reaction Steps

100 parts of hydrogenated polyisoprene glycol (PIP-H, average molecular weight of 2,500, made by Idemitsu Petrochemicals Corp. Japan), 35 parts of epichlorohydrin, 16 parts of pelletized sodium hydroxide, 1 part of benzyl trimethyl ammonium chloride and 50 parts of toluene were fed and reacted under a vigorous stirring at 50 degrees C. for 5 hours in the nitrogen atmosphere. After the reaction, 100 parts of water were added and the product was washed while stirring for 10 minutes. After laying it quietly, the upper layer was separated and filtered, and then the remaining epichlorohydrin and toluene were removed under vacuum. Thus 90 parts of glycidyl ether of hydrogenated polyisoprene glycol (a) was obtained as a residue. This glycidyl ether (a) had an epoxy equivalent weight of 1,650 g/eq.
